1 Claim. (Cl. 131-225) This invention relates to new and usefulimprovements in a smoking pipe.

In most of the commercial smoking pipes, the bowl is formed with eitheran integral stem or with a short extension to which the stem is joined.This necessitates using stock of considerable length and width in orderto form the bowl.

It is a prime object of the present invention to provide a smoking pipewith separate bowl and stem portions, the bowl being formed without astem or stem extension.

Another object of the invention is to provide a smoking pipe withseparate bowl and stem portions formed .of briar wood so as to utilizethe short blocks and lengths of briar wood in the formation thereof.

A further object of the invention is to provide a smoking pipe withseparate bowl and stem portions embodying a novel leakproof jointbetween said portions without the use of metal parts.

It is further proposed to provide a smoking pipe with separate bowl andstem portions which are readily assembled by a single operation.

It is also an object of the invention to provide a smoking pipe which issimple in construction and which can be manufactured and sold at areasonable cost.

Other objects and advantages of the invention will be apparent from thedescription thereof to follow taken in conjunction with the accompanyingdrawings in which:

Figure 1 is a fragmentary longitudinal vertical sectional view throughthe center of a smoking pipe made in accordance with the invention.

Figure 2 is a side elevational View of the bowl of the pipe.

Figure 3 is a rear view thereof.

Figure 4 is a bottom plan view thereof.

Figure 5 is a side elevational view of the stem of the pipe.

Figure 6 is a view of the left hand end of the stem shown in Figure 5.

Figure 7 is a top plan view thereof.

Referring to the drawing in detail, a smoking pipe, comprising a bowl 1,a separate stem 2 and a separate bit or mouthpiece 3 is shown inFigure 1. The bowl is readily formed from a small block of briar woodand the stem from a short length of the same material. The bit ormouthpiece may be formed of rubber, rubber composition or plastic orother suitable material.

The bowl 1 comprises the usual substantially cylindri cal upstandingwall 4 enclosing a tobacco chamber 5 and having a bottom portion 6. Asmoke passage 7 formed in the bottom portion 6 communicates with thechamher 5.

According to the present invention the bowl 1 has a flat rear surface 8that is normal to the longitudinal axis of the stem and in which is adovetail groove 9 that is formed by the undercut side walls 13 whichextends from the bottom surface of the bowl toward the top of the bowland merge into an undercut top wall 2,918,067 Patented Dec. 22, 1959 15and a surface 12 that lies in a plane normal to the smoke duct 19 on thelongitudinal axis of the stem. At the upper end of the flat surface 8and projecting angularly therefrom is an arcuate wall 11.

The stem 2 is cylindrical in cross-section and is formed with a flatsurface 25 at one end and an extension 17 on said end, of dovetailformation and of a shape similar to the groove 9 in the bowl 1.Extension 17 projects centrally and transversely of the flat surface onthe end of the stem from the lower side of its periphery and terminatesjust short of the opposite or upper side thereof, the bottom side 18 ofthe extension being arcuate in shape and the end 26 of the extensionbeing fiat. An axially disposed smoke passage 1? is formed in the stemand terminates at its rear end in a tapered recess 20 for frictionallyreceiving and holding the tapered end 21 of the bit or mouthpiece 3which is provided with the usual axial smoke passage 22.

In assembling the bowl and stem, in a single operation, the dovetailextension 17 on the stem is slid upwardly through the opening in thebottom end of the groove 9 in the surface 8 in the bowl 1 therebyinterlocking the slanting side edge surfaces 23 and the top surface 24of the extension 17 of the stem with the similarly shaped undercut sidewalls 13 and inner end wall 15 of the groove. When the parts are thusinterlocked as shown in Figure l, the flat end surface 25 of the stem 2which borders the side surfaces 23 and top surface 24 seats on the flatsurface and the fiat end surface 26 of the extension 17 seats on thefiat surface 12 of the groove, with the arcuate surface 13 of theextension meeting the bowl surface at the bottom of the bowl, thesurface of said end 18 being complemental to the bottom portion 6 of thebowl. The interlocked parts are preferably secured in position bysuitable adhesive placed on the abutting surfaces thereof. A sealed,leakproof joint is thus constructed between the bowl and stem of thepipe, without the use of metal parts or auxiliary instruments. The bitor mouthpiece 3 may readily be inserted endwise into the recess 21? inthe outer end of the stem 2 and is frictionally held therein as will beunderstood.

While I have illustrated and described the preferred embodiment of myinvention, it will be understood that changes in details thereof mightbe made without departing from the principle of the invention and Idesire to be limited only by the state of the prior art and the appendedclaim.

What I claim is:

A smoking pipe comprising a bowl and a separate stem connected by ajoint between them, wherein said bowl has a fiat rear surface in whichis a dovetail groove formed by slanting side walls extending from thebottom surface of the bowl toward the top of the bowl and merging into aslanting top wall, and said separate stem has a dovetail tenon at oneend thereof with slanting side and top surfaces bordered by a fiat endsurface, with said side, top and flat end surfaces in tight abuttingcontact with the side walls, and top wall of said recess and said fiatrear surface of the bowl, respectively.
